Navigating Data in the Table Viewer

Most OLAP cubes contain too much data to be displayed in the table viewer at one time. Navigation features enable you to view data that is not shown in the initial display, or to focus on a subset of the data.

Using navigation features in SAS Web OLAP Viewer, you can perform the following tasks:

• Scroll through Columns and Rows
• Resize Headings
• Expand and Collapse Hierarchy Members
• Drill Down on Hierarchy Members
• Isolate a Hierarchy Member
• Show Detailed Data

If a subset of the columns or rows in the table viewer can fit on the screen at one time, the lower-left or upper-right corner of the table will contain a navigation bar like this:

The navigation bar contains the following information:

• the rows and columns that you are currently viewing
• the total number of rows or columns

The following buttons are available for navigating columns:

The following buttons are available for navigating rows:

To resize the headings in the table, click the edge of a heading and drag it to the width that you want.

You can resize the innermost headings on the horizontal axis. You can also resize the hierarchy level and measure headings on the vertical axis.

In the initial display for the table viewer, only the top-level members are shown for each hierarchy. To see the lower-level members within a hierarchy, you must expand the top-level members.

To expand a single member, click . To collapse the member again, click .

To expand all members at a specific level, click on a level heading and select Expand All from the pop-up menu. To collapse the members again, click on the level heading and select Collapse All from the pop-up menu.

You can focus your view on a specific hierarchy member by drilling down on that member. Click for the member that you want to drill down on.

When you drill down on a member, that member becomes the top-level heading for the hierarchy that it is a member of. The drill-down context appears in the Drill Path viewer.

For example, if you drill down on the member 2001 of the dimension TIME, the context TIME > 2001 appears.

To drill back up, click on the member that you want to drill to in the Drill Path viewer. In the preceding example, you would click on the top-level member, TIME. You can also drill up in a hierarchy by clicking a level heading within the hierarchy and selecting Up to level-name.

Using the drilling controls in SAS Web OLAP Viewer, you can drill down multiple times within the same hierarchy. You can also drill down in multiple hierarchies. For example, if a table contains the TIME and GEOGRAPHY dimensions, you might focus on data for the first quarter of 2003, and for the Northeast region, by drilling down to TIME > 2003 > 1 and GEOGRAPHY > NORTHEAST.

You can minimize (), restore (), or remove () the Drill Path viewer by using the appropriate buttons.

You can focus on the data for a specific hierarchy member by isolating that member. Right-click the member that you want to isolate, and then select Isolate member-name.

When you isolate a hierarchy member, that member is the only member that is displayed from that hierarchy. A filter is automatically created to select the isolated member, and a drill-down action is also created if the isolated member is not the top-level member.

For example, if you isolate the member 2007 in the TIME dimension, then the filter Time: 2007 is created.

To undo the isolation, open the Filters dialog box and clear the filters for the dimension that contains the isolated member.

For some OLAP cubes, you can view the underlying data table by using the Detail Data dialog box.

You can open the Detail Data dialog box by using either of the following methods:

• Click on any cell value.
• Right-click on any measure or hierarchy member and select Show Detail Data.
